Doesn't matter whether or not it's "macho" to get hit with it over seeing it. There needs to be an option for learning healing Blue Mage skills in these various Blue Magic scripts other than "install a script that lets you manipulate enemies."
Confuse your enemy and hope he heals you. Blue mages are about the most versatile classes in every FF game, it isn't like the class can't function without healing.
Having a means to control your enemy is probably the easiest (and best) way to accomplish what you want. You're not lagging up every battle checking for conditions that probably won't be there, and you also get the benefit of using that control to learn "harmful" spells as well - this was the only way to get some of those spells (or at least to get them early in the game) in a couple FF titles.
I'd love to see it attached to the actor rather than the armor, but I'm not going to say it isn't usable that way. In some ways it's better - sort of like a dual class character.
